Summary

To evaluated the clinical performance of composite resin restorations, considering also the evaluation of release of resin components into saliva and the presence cytokines in gingival fluid. Restorative system FL-Bond II (self-etching adhesive system)/ beautifil II (composite restorative) were use. For in vitro assays, adhesive and resin specimens are being preparing for assessing the monomers degree of conversion (by FTIR), sorption and solubility and release of resinous components in ethanol and Ringer solutions (through a gas chromatography and mass spectroscopy - GC-MS). In the longitudinal clinical study clinical performance of restorations and periodontal response were evaluate.

Detailed description

Release of components of a resin composite system containing pre-reagent vitreal particles: laboratory and patient studies. The objectives of this study was to evaluate physical and chemical properties of a methacrylate-based restorative system regarding to the release of resin components to the storage medium, to evaluate the clinical performance of composite resin restorations, considering also the evaluation of release of resin components into saliva and the presence of cytokines in gingival crevicular fluid. Restorative system FL-Bond II (self-etching adhesive system)/ beautifil II (composite restorative) were use. For in vitro assays, adhesive and resin specimens are being preparing for assessing the monomers degree of conversion (by FTIR), sorption and solubility and release of resinous components in ethanol and Ringer solutions (through a gas chromatography and mass spectroscopy - GC-MS). In the longitudinal clinical study, patients who present a NCCL with restorative need were selecting. Prior to treatment, there will be periodontal evaluation, saliva and gingival crevicular fluid collection (controls). The lesions were restoring with the restorative system. After 10 min,7 days, 1 and 6 months, clinical performance of restorations and periodontal response were evaluate according to the criterion FDI. Additionally, in all of these evaluation periods samples of saliva and crevicular fluid are being collecting. Saliva samples will be analyze by GC-MS to identify the eventual presence of organic components derived from the restoration. The crevicular fluid samples were analyzing using ELISA for identification and quantification of interleukins.
